According to Production Weekly, the working title for Sony and Marvel's Spider-Man reboot (listed as "Untitled Marvel/Sony Feature") will be: "Summer Of George." The title appears to be a reference to a 1997 episode of Seinfeld.
"Summer Of George" was the title for the Season 8 finale (156th episode) of the NBC sitcom. In it, lovable loser George Costanza receives a severance package from the New York Yankees, and it's enough money for George to do whatever he likes for the summer, but instead he chooses to waste his financial freedom by being incredibly lazy.
The Spider-Man reboot will star Tom Holland and Zendaya. It'll be directed by Jon Watts, based on a script written by John Francis Daley and Jonathan M. Goldstein.
Sony's Spider-Man reboot will swing into theaters July 7th, 2017.
